Health officials: West Africa Ebola toll hits 1,229

Cases in West Africa's Ebola outbreak have risen to 2,240 this year, including 1,229 deaths, the World Health Organisation (WHO) says.

The organisation said it is working with the UN's World Food Programme to ensure food delivery to 1 million people living in Ebola quarantine zones in Guinea, Liberia and Sierra Leone.

"Food has been delivered to hospitalised patients and people under quarantine who are not able to leave their homes to purchase food. Providing regular food supplies is a potent means of limiting unnecessary movement," WHO said in a statement.
